cmd/compile: don't treat an InlMark as a read during deadstore
An InlMark "read" can't make an otherwise dead store live. Without this
CL, we sometimes zero an object twice in succession because we think
there is a reader in between.
Kind of challenging to make a test for this. The second zeroing has the
same instruction on the same line number, so codegen tests can't see it.
Fixes #67957
